Hi! I was trying to use this ActitioN8 with Dwarf but I get this error via dmesg
[ 2742.198270] usb 2-1: new low-speed USB device number 8 using ohci-platform
[ 2743.165313] usb 2-1: New USB device found, idVendor=552d, idProduct=002a, bcdDevice= 0.01
[ 2743.165341] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 2743.167329] usb 2-1: can't set config #1, error -62
[ 2743.167930] usb 2-1: USB disconnect, device number 8
The controller works just fine with windows and MIDI-OX monitor.
Nux mg-30 has midi over usb type-C port but it has no midi host capability.
I think if I connect mg-30 to m-vave chocolate midi with a usb type-C to type-C cable it shouldn’t work because none of them has usb midi host feature (indeed you have to buy the bluetooth-usb dongle that has midi host capability: the dongle receives midi via bluetooth from midi chocolate and then sends midi via usb cable to nux).
looks really nice and clean. Its probably a barbones arduino (chip is the same) with a custom bootloader and without the usb interface (needed for easy programming with arduino ide)
Again your best bet would be to replace the board with an arduino and the USB HostBoard
